摘要
为了了解驾驶员在高原低氧路段行车时,道路纵断面线形对肌电特性指标平均功率频率MPF的影响,使用生物反馈检测仪记录在高原公路行车驾驶员的肌电信号,结合G314路线纵断面图,分析在高原公路行车驾驶员的MPF的变化规律。定量分析MPF与海拔高度、竖曲线半径以及坡差间的关系。研究表明:在高原公路行车时,海拔高度是影响驾驶员MPF值变化的主要因素;其与坡差呈负相关;海拔高度与竖曲线半径存在共线性关系,伴随海拔高度的升高和竖曲线半径的减小,MPF值迅速减小。
In order to understand the driver s influence on the myoelectric characteristic index MPF when driving on the plateau low-oxygen section,the longitudinal profile of the road,the myoelectric signal of the driver on the plateau road was recorded using a biofeedback detector.Combining the longitudinal profile of the road G314 route,the change law of MPF in the driving of the plateau highway was analyzed.Quantitative analysis of the relationship between MPF and altitude,vertical curve radius and slope were given.Research shows that altitude is the main factor affecting the change of driver s MPF value when driving on highland highways;it is negatively correlated with the slope difference;there is a collinear relationship between altitude and vertical curve radius;with the increase of altitude and the decrease of vertical curve radius,MPF value decreases rapidly.
